Im getting a clang-tidy error on osapi.cpp after incomporating the last few commits into my branch #6992 , nothing i did is related to that, but im getting this error because im modifiying that file.

fs2open.github.com/code/osapi/osapi.cpp

Line 908 in cb284b7

extern const char* Osreg_user_dir_legacy;

clang-tidy: redundant 'Osreg_user_dir_legacy' declaration (readability-redundant-declaration)
Check a pull request / Linux (Debug, clang-16)

Im not sure what to do here.

As the definition of that error states:

Such redundant declarations can be removed without changing program behavior.
